absolute best shop in the area is magnum collision. They do all the high end cars. Check them out

I will agree with magnum. I have had one of my cars in there and they do good work.
Stay away from Performance auto is Roswell/ Alpharetta. I have had the same car in there 2 times and it has never been 100%. Had paint drips in 3 diff areas and the blend is pretty crappy.
